MODE 0F ATTACHING- HUBS TO AXLES.

Specification of Letters Patent No. 17,063, dated April 14, 1857.

To all whom t may concern.'

Beit known that I, LoEENzo WrNsLow, of Rochester, in the county of Monroe and State of New York, have made and invented certain new and useful Improvements in the Mode of Connecting the Boxes of Carriage-Wheels with the Axles; and I do hereby declare the following to be a full and accurate description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, same letters referring to like parts in all the drawings.

Of said drawings. Figure l is a sectional elevation of the box. Fig.f2` is an elevation of the corresponding arm of the axle. Fig. 3 is a sectional elevation of both the above when combined, and Figs. 4, 5 are certain explanatory details. 4

The arm of the axle is formed substantially as seen in the drawings, the bearing surface extending from the shoulder to the point. The box is of course bored out to fit accurately the portion of the arm from A to B, with the `exception of the space at the point D which is left to receive oil. At B Fig. l the box is enlarged as seen in the drawing and is made to receive the two rings or collars a and b (Figs. 3 and A). One of these rings is iirmly attached to the arm by the pin 79 passing through both; while the other ring b is secured'by one or more pins or screws to the box-all which will be clearly seen on inspecting the drawing Fig. 3. y

It is now evident that while the box is free to revolve on the axle it cannot be pulled off owing to the arrangement and mode of fastening of the rings a and b. `But at the saine time the box and with it the hub, may be very easily detached from the axle by simply taking out the pin p; while on the other hand it may be securely attached by the insertion of the same pin. The pin p is inserted through holes in the possible for it ever to get outas Ait is covered by the box and thimble. And as the head of said pin is made slightly rounding even if it should happen to spring up a little when the hole in the box waspassing over it, it would be immediately pressed back again to its place. The pin is made slightly tapering toward the point so that it- Inay not fall through the hole; and the hole is made to slant as shown in Fig. 5 by which means the blow produced by striking against any obstacle (O) will fall more nearly at right angles to the axis of the pin 7J and will have `no tendency to impart a longitudinal motion to it.

The thimble T is of the usual construction and is designed toexclude dirt and grit from the arm and box where they join.

The advantages of this construction of axle are its simplicity and the ease with which it may be manufactured; its convenience and safety inV use-there being no screws to work loose and roll olf; and finally its freedom from all leakage of oil on the outside of the wheel-a feature common to most axles and boxes and one not only unsightly but inconvenient.

Having thus described my invention what I claim therein as new and desire to secure by Letters Patent is- The method herein described of attaching the boxes of carriages to the axles thereof by means of the ring a and pin p operating in combination with the ring Y) and pin or pins c c in the manner set forth.
